如何发送静默的推送通知有效负载

问题描述：

我只想知道如何确定对无声推送执行的操作:

I just want to know how I can determine what action to do on a silent push:

这是我发送给客户端的aps:

This is the aps that I sent to the client:

"aps": {
    "content-available": 1
}

现在的问题是，当我添加type: "Order_Update"以确定静默推送是为了让订单更新"显示警报通知时.

My problem now is when I add type: "Order_Update" to determine that the silent push is for the Order Update to display an alert notification.

有一些选择！让我们花点时间了解所有不同的有效负载及其用法.

There are a few options for it! Let's take a small ride to understand all the different payloads and their usage.

简单有效载荷

显示在通知中心中:是

唤醒应用程序以执行后台任务:否

Wakes app to perform background task : No

{
    "aps" : {
        "alert" : "You received simple notification!",
        "badge" : 1,
        "sound" : "default"
    }
}

带有自定义通知声音的负载

显示在通知中心中:是

唤醒应用程序以执行后台任务:否

Wakes app to perform background task : No

Step 1:在应用程序包中添加自定义通知声音文件(仅.wav或.aiff扩展名，例如notification.wav).

Step 1 : Add custom notification sound file (.wav or .aiff extensions only. e.g. notification.wav) in your app bundle.

Step 2:如下所示配置有效载荷以播放自定义声音

Step 2 : Configure your payload as shown below to play your custom sound

{
    "aps" : {
        "alert" : "It's a custom notification sound!",
        "badge" : 1,
        "sound" : "notification.wav"
    }
}

自定义有效负载通知

显示在通知中心中:是

唤醒应用程序以执行后台任务:否

Wakes app to perform background task : No

{
    "aps" : {
        "alert" : "It's a notification with custom payload!",
        "badge" : 1,
        "content-available" : 0         
    },
    "data" :{
        "title" : "Game Request",
        "body" : "Bob wants to play poker",
        "action-loc-key" : "PLAY"
    },

}

在这里data词典可保存您想要的自定义信息.它还将显示为带有警报消息这是具有自定义有效负载的通知！"的正常通知.

Here the data dictionary holds custom information whatever you want. It will also display as normal notification with the alert message "It's a notification with custom payload!".

正常静默通知

它不会在通知栏上显示警报；它只会通知您的应用程序有一些新数据可用，提示应用程序获取新内容.

It will not a show an alert as a notification bar; it will only notify your app that there is some new data available, prompting the app to fetch new content.

显示在通知中心:否

唤醒应用以执行后台任务:是

Awake app to perform background task : Yes

{
    "content-available" : 1
}

具有自定义有效负载的静音通知

在这里，魔术可以显示通知警报，并在后台唤醒您的应用以执行任务！ (注意:仅当它在后台运行并且未被用户明确杀死时才如此.) 只需在有效负载中添加额外的参数"content-available" : 1.

Here comes the magic to show a notification alert as well awake your app in background for a task! (Note: only if it's running in background and has not been killed explicitly by the user.) Just add the extra parameter "content-available" : 1 in your payload.

显示在通知中心中:是

唤醒应用程序以执行后台任务:是

Wakes app to perform background task : Yes

{
    "aps" : {
        "alert" : "Notification with custom payload!",
        "badge" : 1,
        "content-available" : 1
    },
     "data" :{
        "title" : "Game Request",
        "body" : "Bob wants to play poker",
        "action-loc-key" : "PLAY"
     }
}

根据您的应用程序要求使用任何这些有效负载.对于background app refresh，请参考

Use any of these payloads according to your app requirements. For background app refresh refer to Apple's documentation. I hope this gives you all the necessary information. Happy coding :)
